Zodiacal Exoplanets in Time (ZEIT) XII: A Directly-Imaged Planetary-Mass Companion to a Young Taurus M Dwarf Star

E. Gaidos, T. Hirano, A. L. Kraus +21

We report the discovery of a resolved (0".9) substellar companion to a member of the 1-5 Myr Taurus star-forming region. The host star (2M0437) is a single mid-M type ($T_{eff}\app…

First Detection of Hydroxyl Radical Emission from an Exoplanet Atmosphere: High-dispersion Characterization of WASP-33b using Subaru/IRD

Stevanus K. Nugroho, Hajime Kawahara, Neale P. Gibson +23

We report the first detection of a hydroxyl radical (OH) emission signature in the planetary atmosphere outside the solar system, in this case, in the day-side of WASP-33b. We anal…

ALMA observation of the protoplanetary disk around WW Cha: faint double-peaked ring and asymmetric structure

Kazuhiro D. Kanagawa, Jun Hashimoto, Takayuki Muto +13

We present Atacama Large Millimeter/submillimeter Array (ALMA) Band 6 observations of dust continuum emission of the disk around WW Cha. The dust continuum image shows a smooth dis…

Precision radial velocity measurements by the forward-modeling technique in the near-infrared

Teruyuki Hirano, Masayuki Kuzuhara, Takayuki Kotani +15

Precision radial velocity (RV) measurements in the near-infrared are a powerful tool to detect and characterize exoplanets around low-mass stars or young stars with higher magnetic…

Zodiacal Exoplanets in Time. XI. The Orbit and Radiation Environment of the Young M Dwarf-Hosted Planet K2-25b

E. Gaidos, T. Hirano, D. J. Wilson +20

M dwarf stars are high-priority targets for searches for Earth-size and potentially Earth-like planets, but their planetary systems may form and evolve in very different circumstel…

Limits on the Spin-Orbit Angle and Atmospheric Escape for the 22 Myr-old Planet AU Mic b

Teruyuki Hirano, Vigneshwaran Krishnamurthy, Eric Gaidos +19

We obtained spectra of the pre-main sequence star AU Microscopii during a transit of its Neptune-sized planet to investigate its orbit and atmosphere. We used the high-dispersion n…
